Be it -know'n that I, WILLIAM .LA-Miroir,l a clti'zen of theUnitedStates,` andv a resident; of

-yl'ola, -Allen county, Kansas, have invented certainfnew andjusefulImprovements in Zinc-Smelting Furnaces ofy which the following is aspecification containing va full,

' clear, and exact description, reference being v v*had totheaccompanying daWgSf forming y IO n a parthereof.

'My invention relates to zinc-vsmelting fur` i haces', and particularly'to .a furnace for the .heating of retorts used in thedistillationofgradual and perfect combustion of the fuel zinc ores and oxids intometallic zinc.

'The'primary-object of my invention is the arrangement ofa zinc-furnace`whereby a used for heating is obtained,- thereby producingnotonlyeconomy in fuel, Vbut at the same time'L 4a more unifo'rmfandydesirable 'character of `combustion and consequent f steadiness oftemperature in the retort-fur` nace chamber which results are highlyessen-` tial forthe proper volatilization anddistillation of, themetallic zinc`gand likewise the. savingv of the retorts or mufiies fromde= struction usually vresultin from spotted, ir-j` regulan'anduncontrollab e heats, as is thef case in many furnaces heretoforeconstructed. l By my improved vconstruction the fuel .f is

v taken in atfthelower end or bottomofthe f furnace-chambers,v wheresaid fuelris ignited and the firefandv heat thus obtained naturally;

pass upwardlythrough the retort-chambers7 strikeagainst the furnace roofor arch, and arev deflected `thereby downwardly, y and vthe j iame andheat are'withdrawn from outlets This arran e` ment, togetherwiththe'admission of.`air orl combustion atfthe proper points, producesav 'condition wherebytheair and gases-are veryy easily rmixed yandintermingled, which .natu-i rally results in an easilyiregulatedjperfectA 1 y 2 of the furnace, and the compartments 11 The `construction*herein shwn and de-"f scribed is `designed .tov operate-with natural'"or artificialfgas orl any other suitable oil or] n i do not extendallthev way to the arches 4,

I To the above purposes my invention consists in certain'new and novelfeatures of con-k struction, which will -be hereinafter morefullysetforth, pointed out in theclaims, and Iillustratedin theaccompanying drawings,

side walls l'to'thecenterwall 3, and extendroo furnace between thesidewalls and center wall are the retorts 12, which are of the ordinaryconstruction.

Formed in the base of the center wal-l 3 at each end of the furnace andextending inward as far as the partition-walls 9 are airinlet ducts 13,and leading therefrom outward through the base of the wall 3 anddischarging into the chambers 1() are the horizontally-arrangeddischargelopenings 14.

Leading upward through the bottom of the -furnace into the baseof thecenter wall 3 is a -series of passages 15, the upper. ends of which.

extend horizontally through the base of the center wall 3, as designated(by 16, and discharge into the chambers 10, there being preferably oneof these inlets 15 and discharge-openings 16 foreach one; of theopenings 14.

Arranged in a suitable chamber beneath the furnace are gas-mains, suchas 17, and vleading therefrom into each one of the passages 15 is adischargenozzle 18.

Leading inwardly from the end walls 2 of the furnace through the upperportionof the center wall 3 and adjacent the arches 4 are .air-inletpassages 19, which extend to the .partitions 9, and leading from saidinletpassages through the center wall 3 into the upper lends of thechambers 11 are the dischargeopenings 20. A series of air or air and gasinlet passages 21 are transversely arranged in Athey end-.walls 2 andextend from the side walls 1 to the center wall 3, and each one of these-passages 21 is intersected by inlet-openings '22, whichA are formed inthe end walls 2 *and which discharge into the outer ends of I.fthechambers 10.

Formed in the center f'w'al'l 3l and extending from one partition9 tolof which discharges intothel horizontal fiue 5.

"the other v-and between the compartments 11 is avertically-disposedflue 2 3, the upperend 'The lower end of this fiue.23 issom'ewhat wider than the upper portion,.'andlongitu''dinally-disposed in said widened* lower end is "abaffleplate 24, whichextends from one end ,'"f'said iiue to the other. Leading through g'the'base of the 'center wall 3 from the lower l"eil-'dief the flue 23 to the.chambers 11, are the Ahorizontally-disposed openings 25.

The construction as just described, and as shown in the accompanyingdrawings, provides for two single-retort furnace-chambers.

arranged back to. backor divided by the center wall 3 and havingnocommunication with eachother.

Each chamber comprising the compartments and 11 contains the retorts,and the space between and around the retorts in the chambers 10 isutilized for conducting the burning gases upward, and the space betweenand 'around the retorts in the chambers 11 is utilized for conductingsaid burnfurnace is identical.

ing gases downward, while the arrangement of gas and oil inlet iiues atthe ends of the The gas or fluid fuel utilized for heating the furnacedischarges from the nozzles 18' upwardly through the passages andhorizontally outward through the openings 16. Here said gas or fluidfuel becomes mixed with air entering the passages 13 and 15 anddischarging through the openings 14 and 16, and thus the mixed gas andair enters the chambers 10 and is ignited. The explosive effect of themixture and the ignition of the air and gases aslthey meet in thebottoms of the chambers 10 carries them upward through the space-between and around the retorts in said chambers until they finallyreach the arches 4, where they are thrown backward, and at the same timethey are thrown toward the center of the furnace by the natural draft,and after passing through the spaces above the partitions 9 said ignitedgases pass downward through the space between the retorts in thechambers 11, and finally discharge through the openings and pass fromthence upward through the flue 23 to and through the flue 5 and into thestack 6.

Additional air, or a mixture of air and gas, may be discharged into theupper ends of the compartments 10 through the passages 1Q and openings20, the` outer ends of which passages 19 can be partially closed bytemporary fillings or suitable. draft-regulating devices. In the samemanner additional air or a combination of air and gas may be dischargedinto the ends of the chambers 10 through the passages 21 and openings22, the outer ends of which may be partially closed by temporaryfillings or draft-regulating devices.

Suitable draft-regulating devices may be, A

' gases upward through the flue 23.

The draft of the furnace, as shown and d escribed, is produced by astack or chimney; but this is not essential, inasmuch as the draft maybe produced by moans of an cxhaust-fan or by forcing the air and. gasinto the furnace by pressure.

1 desire to call especial attention to the arrangement of the centerwall between the two retort-chambers and the constructionv of said wallfor the purpose of throwing off the products of combustion after thesame have passed through retort-chambers, which arrangement economizesspace in the con- IOO lIO

v *IJ do not.desireftoflimitinyself.to the exact details ,ofconstruction herein shown `and specified, as slight [variations may-bemade without "departing from the vspirit of my invention. For instance,the lsame jresult could be obtained and 'theA same principles would beinvolved if the burning gases were conducted upward through the Vspacebetween one-half or two-thirdsofxthe retorts 'and thence drawn downwardat the opposite ends ofsaid furnace,v and means whereby the air andgas'during combustion are `[caused to pass upward-between the retortsvinthe ends of the furnace, downward between the retorts in the center ofthe furnace, and thence outward through the `flue in the center wallsubstantially asspecified. f
